- Аннотация: MASTER-SAAO robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB 221223A ( Fermi GBM team, GCN 33096) errorbox 72801 sec after notice time and 72834 sec after trigger time at 2022-12-24 20:10:01 UT, with upper limit up to 18.2 mag. The observations began at zenith distance = 61 deg. The sun altitude is -24.2 deg. The galactic latitude b = -67 deg., longitude l = 71 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2186850 We obtain a following upper limits.
